Shortcode is the one of powerful feature in Wordpress which provides so much flexibility to enhance functionalities. Sometime you need to detect if current post/page have already specific shortcode. Here is the following two snippets which you could use for check specific shprtcode into your shortcode callback function. Snippet -1(Using has_shortcode() function) <?php add_shortcode('shortcode_name','shortcode_callback'); function shortcode_callback($atts){ global $post; $shortcode_feature = ' '; if (has_shortcode( $post->content , ' shortcode_name ' )){ // Apply your specific code here. } // Do whatever you want return $shortcode_feature; } Snippet -2 (Using strpos() function) $shortcode = '[shortcode_name'; $check = strpos( $post->content,$shortcode ); if ( $check !== false ) { //Return already matched } Prefer to use Snippet-1 using default function of wordpress.
